Rl. Frei et Ma. Mcdaniel, VALIDITY OF CUSTOMER SERVICE MEASURES IN PERSONNEL-SELECTION - A REVIEW OF CRITERION AND CONSTRUCT EVIDENCE, Human performance, 11(1), 1998, pp. 1-27
The criterion-related and construct validity of customer service orien
tation measures were examined using quantitative review methods and la
rge samples of primary data. The criterion-related validity analysis w
as based on 41 coefficients with a total sample size of 6,945. The mea
n validity was .50 for an aggregated supervisory rating of job perform
ance. The construct validity evidence indicated that customer service
measures were positively and strongly related to personality dimension
s of agreeableness, emotional stability, and conscientiousness. Custom
er service orientation was moderately related to sales drive and socia
l interests but was uncorrelated with cognitive measures.
